Ive had an Iphone 4 for a while now (nearly over a year) and ive got the lastest update (iOS 6.1.3) but ever since I restored my phone ages ago I lost access to use FaceTime. Before I restored it I was able to FacTime different Iphone and Ipod users but now I'm not able to. My sister has an Iphone 4 just in black and she is able to FaceTime so I assume theres nothing new (like an update) my phone needs to be able to FaceTime.
Ive looked on the internet for answers and none of them seem to help. Most answers contain things like going onto settings and activating FaceTime, but I dont seem to have the app on my phone nor do I have the option to active FaceTime by going on to settings and then phone. I need help urgently as it's really starting to bug me.
Any answers would be most appreciated and useful.
